l' ATS STERILIZERJAUCET.

K To all whom t may concern:

Be it known that l, EDWARD CHARLES SPURGE, a subject of the KingofEngland, residing at Niagara Falls, New York, have invented new anduseful Improvements 1n Sterilizer-Faucets, of which the following is afull and clear specification.

My invention relates in general to sterilizer faucets and moreparticularly to that class of faucets which have means for. drawing inthe sterilizing gas by the suction action of the flowing water, andmeans for simultaneously turning on the water supply and closing ltheelectric circuit through the ozonifier or other sterilizing gasproducing means. The principle of this construction is to make thesupply of sterilizing gas dependent upon the use of the water, and lbycontrolling the supply of current for the production of the sterilizinggas simultaneously with the flow vof the water, it is obvious the dangerof supplying water which is not sterilized and the ineconomy ofproducing sterilizing gas at times other than when required forimmediate use are avoided. |The sterilizing gas will in most instancesbe ozone or ozonied air and hence I shall refer herein to thesterilizing gas as ozone, it being understood that the operation of theparts will be the same regardless of the particular properties of thesterilizing gas itself.

It' has already been proposed to operate the electric switch and watervalve by a single lever or equivalent means which initially closes theelectric switch and subsequently moves upon the circuit closmg means asa fulcrum toeffect the opening of the water' valve.

My invention in relation to this feature resides in an improvedconstruction and operation of these elements. It has also been proposedto effect the cooling of the ozonier by the flow of water to besterilized.

My invention comprises an improvement in this feature by means of whichthe cooling water is controlled by the same valve which opens or closest-he pipe or other conduit for the water ,to be sterilized, and in suchmanner that the cooling water is in'- dependent of the water which hasalready been sterilized by the action of the ozone.

An embodiment of the invention is illustrated in the accompanyingdrawings, in which- Y Figure 1 is a more or less diagrammaticSpecification of Letters Patent.

View of the essential parts of the apparatus. Fig. 2 is a verticalsection taken through the electric switch and water valve, and Fig. 3 isa front elevation of the electric switch with the cover removed.

Referring now more specifically to said drawings, 10 indicates the watersupply pipe to which is to be connected the sterilizer faucet. Thefaucet comprises a main casting forming the water conduits 11l and 12,between which communication is controlled by the valve 13 normally heldagainst valve seat 14 by compression spring 15 seated in plug 16 whichis threaded into the bottom opening of the faucet beneath the valveseat. passes through a guide bearing 18 and is surrounded by a packing19 and gland 20. The upper portion of the valve stem is slotted and inthis slotted enol is pivoted by pivot pin 21 the double fulcrum lever22. The latter is operated by a cam lever 23 having a handle portion 24which is pivoted in the slotted upper end of a vertical post 25, inwhich the forward end of the double fulcrum lever 22 moves. Between thelower surface of the double fulcrum lever 22 and the bottom of therecess in the post 25 is confined a return spring` 26 which tends toelevate the forward end of the double fulcrum lever 22.

Integral with or secured to the rear portion of the casting of thefaucet is a standard 27 upon which is mounted theelectric circuithousing 28 which has a cover plate 29 secured thereon by means of screws30 which are threaded into lugs 31. Extending forwardly from the lugs 31are beveled flanges or seats 32 which receive a transverse plate ofinsulation such as fiber or the like 33, in which are mounted thecircuitterminals 34. Below the transverse plate 33 the housing 28 is perforatedto receive a push button 35 which carries at its upper end the bridgingcont-act plate 36 for the terminals 34, and between Vthe bottom of thehousing 28 and the enlargement 37 of the push button 35 is confined apressure spring 38 whichtends normally to lower the bridg ing contactplate 36. The enlargement 37 is disposed immediately above the rear endof double fulcrum lever 22, so as to be operated thereby. Upon thedepression of the handle 24 of cam lever 23 the double fulcrum lever 22initially oscillates upon its *fulcrum 21 and raises the push button 35rlhe `valve 13 has a stem 17 which- 'and the contact plate 36 until thelatter engages the terminals 34 and closes the circuit. Furtherelevation of the rear end of the double fulcrum lever 22 is thusimpossible and hence the continued depression of the handle 24 of camlever 23 lowers the valve stem `17 to open the water valve 13. Duringthis latter operation the fulcrum of the lever 22 is near its rear end.It should lalso be stated that the springs l5 and 3S are so proportionedas to prevent the operation of the valve stem. until the electric switchis firmly closed.

vWhen the cam lever 23 arrives at the end of its downward movement theforward end of double fulcrum lever 22 is held in locking engagementwith the cam portion of the lever 23 under the influence of the springs15 and 2G, due to the shape of the cam 23. Fig. 2 shows in dotted linesthe position of the double fulcrum lever and cam lever, at the end ofthe initial movement, whereby the electric switch is closed, and Fig. 1shows in dotted lines the position of the levers 22 and 23 at thecompletion of the second movement, whereby the water valve is opened andthe cam lever 23 held down. It will be apparent that the water willcontinue to How and the electric circuit be maintained as long as thecam lever 23 vis held down and that this position is n1aintainedautomatically by the springs 15 and 2G without the necessity forcontinued manual holding. In order to return the parts to norma-lposition the cam lever 23 is manually thrown upward beyond the point oflocking engagement with the double fulcrum lever 22, whereupon theseveral return springs are free to restore their respective parts toinitial position.

Referring to Fig. 1 the ozoniier is indicated at 39 and the electriccircuit at 40. The ozone pipe 41 leads from the ozonifier 3) into aninjector 42 whereby the flow ot' water through the faucet draws the airinto the ozonifer, and the ozone through the pipe. 4l into the water tobe sterilized. From the injector 42 the ozone and water pass downwardlythrough pipe 43 into the emulsifier 44 of well known construction, asillustrated for example in the United States Patent to Otto, No.837,107. A cooling water pipe 45 is connected with the water conduit 12of the sterilizer 'faucet at connection 4G and leads to the ozonifier 39for use in cooling the electrodes in any well known manner. Y

The operation of the cam lever 23 in opening valve-13 ancl admittingWater into conduit 12 obviously controls the supply of cooling Water tothe ozoniier at the samev 'ing said valve and switch for initiallyclosing the switch and subsequently opening the water valve and a camlever adapted to effect such operation of said double fulcrunl lever andto lock the same in shifted position.

2. The combination with the ozonitler, the water conducting means, thecircuit for supplying current to said ozoniiier, the electric) switchcontrolling same, the injector, the ozone pipe leading from the ozoniierto the injector, the double fulcrum lever operatively engaging the watervalve and electric switch for initially closing the switch andsubsequently establishing the flow of water through the water conductingmeans and injector, and means for operating said dou-` blc fulcrum leverand locking the same in operated position.

3. The combination with water conducting means, the ozonifier, the watervalve for establishingthe flow of water through said water conductingmeans, an injector, the ozone pipe tor leading ozone from the ozonitierto the injector, the cooling water pipe leading to the ozonifier fromthe water conducting means between the water valve and injector, andmeans for opening and closing said water valve.

4. The combination with the water conducting means, the valve forcontrolling the flow of water therein, the ozoniier, the electriccircuit for supplying current thereto, the eletric switch forcontrolling said circuit, the injector, the ozone pipe leading t'rom theozonitier to said injector, the cooling water pipe leading to theozoniier from the water conducting means between the injector and watervalve, and means for simultaneously operating said electric switch andsaid water valve to establish the flow of current through the ozoniierand the iiow of water through the water conducting means.
